Brewing up brain benefits

A recent study led by Assistant Professor Feng Lei from the National University of Singapore (NUS) Yong Loo Lin School of Medicine’s Department of Psychological Medicine revealed that regular tea drinkers have better organised brain regions – and this is associated with healthy cognitive function – compared to non-tea drinkers. The research team made this discovery after examining…

Stopping the seizures

A person with drug resistant epilepsy who gets an early surgical intervention has a better chance of becoming seizure free. This is shown in a systematic review and meta-analysis in which Sahlgrenska Academy researchers, in collaboration with the Swedish Council for Assessment of Health Technology and Social Services (SBU), analysed results from a range of previous studies. They concluded that…

Nanotechnology

The recording of images of the human brain and its therapy in neurodegenerative diseases is still a major challenge in current medical research. The blood-brain barrier, a filter system of the body between the blood system and the central nervous system, constrains the supply of drugs or contrast media that would allow therapy and image acquisition. Scientists at the Max Planck Institute for…

Cognitive Behavioural Therapy

In a new study, led by the University of Glasgow, scientists show that brain activity recorded using functional magnetic resonance imaging (fMRI) may help predict response to CBT in depression before the treatment commences. The advances could help patients receive the most appropriate treatment for depression in a timely manner.

Diagnostic disorder

A new study has concluded that psychiatric diagnoses are scientifically worthless as tools to identify discrete mental health disorders. The study, published in Psychiatry Research and led by researchers from the University of Liverpool, involved a detailed analysis of five key chapters of the latest edition of the widely used Diagnostic and Statistical Manual (DSM), on ‘schizophrenia’,…

Research

Scientists have identified mechanisms in the human brain that could help explain the phenomenon of the 'Uncanny Valley' - the unsettling feeling we get from robots and virtual agents that are too human-like. They have also shown that some people respond more adversely to human-like agents than others.

HeadXNet

Doctors could soon get some help from an artificial intelligence tool when diagnosing brain aneurysms—bulges in blood vessels in the brain that can leak or burst open, potentially leading to stroke, brain damage or death.

Psychiatry

Professor Marco Catani suggests the best explanation for Leonardo da Vinci's inability to finish his works is that the great artist may have had Attention Deficit and Hyperactivity Disorder. Leonardo da Vinci produced some of the world’s most iconic art, but historical accounts of his work practices and behaviour show that he struggled to complete projects. Drawing on these accounts, Professor…

Virtual reality

Virtual reality (VR) can identify early Alzheimer’s disease more accurately than ‘gold standard’ cognitive tests currently in use, suggests new research from the University of Cambridge. The study highlights the potential of new technologies to help diagnose and monitor conditions such as Alzheimer’s disease, which affects more than 525,000 people in the UK. In 2014, Professor John…

Up in smoke

Neonatal exposure to nicotine alters the reward circuity in the brains of newborn mice, increasing their preference for the drug in later adulthood, report researchers at University of California San Diego School of Medicine in a study published in Biological Psychiatry. A UC San Diego School of Medicine team of scientists, headed by senior author Davide Dulcis, PhD, associate professor in the…

Brain tumor

A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors has shown promise in a clinical trial. The imaging system enables neurosurgeons to better see malignant growths that often are difficult to fully eliminate.

Neurology

A new vaccination for malignant astrocytoma brings such patients hope. However, research is still in its infancy. We spoke with Professor Michael Platten, Medical Director of the Neurological Clinic at Medical University Mannheim, about the present state of research and the serious opportunities this presents. During the interview, he also revealed how cooperation with the pharmaceutical industry…

Dementia pathway

A recently recognized brain disorder that mimics clinical features of Alzheimer’s disease has for the first time been defined with recommended diagnostic criteria and other guidelines for advancing and catalyzing future research. Scientists from several National Institutes of Health-funded institutions, in collaboration with international peers, described the newly-named pathway to dementia,…

Post-cancer impairment

Cognitive impairment associated with cancer, also known as “chemobrain”, has gained recognition as a complication of the disease and its treatment, as it can negatively affect the daily lives of cancer patients and survivors. Chemobrain can be subtle yet persistent, with some cancer patients reporting difficulties related to memory and attention even months after completing their treatment.…

Antisocial behaviour

Behavioural problems in young people with severe antisocial behaviour – known as conduct disorder – could be caused by differences in the brain’s wiring that link the brain’s emotional centres together, according to new research led by the University of Birmingham. Conduct disorder affects around 1 in 20 children and teenagers and is one of the most common reasons for referral to child…

Magnetic resonance elastography

The speed of the human brain is remarkable. Almost immediately upon being exposed to stimuli, neurons are activated, prompting subconscious reactions and, a fraction of a second later, thought. But the speed at which we can noninvasively follow brain function using an MRI is not as impressive. Functional MRI (fMRI), which measures changes in blood-oxygen levels, has revolutionized neuroscience by…

Preventing toxic plaques

A protein complex has been shown to play a key role in preventing the build-up of toxic plaques in the brain linked to neurodegenerative disorders such as Alzheimer’s and Huntington’s disease. An international team of researchers from the Universities of Leeds, Stanford (USA) and Konstanz (Germany) have discovered that the nascent polypeptide-associated complex (NAC) helps to prevent the…

CMT, Alzheimer's, Parkinson's

A new study provides critical insight into a little-known, yet relatively common, inherited neurological condition called Charcot-Marie-Tooth disease (CMT). The findings point to a pathway to possible treatments for this disease and better understanding of other neurodegenerative disorders, including Alzheimer's disease, that affect millions. The study focused on two related proteins, MFN2 and…

Neurodegeneration

Inside the body, disease and injury can leave behind quite the mess — a scattering of cellular debris, like bits of broken glass, rubber and steel left behind in a car accident. Inside the central nervous system (CNS), a region that includes the brain and spinal cord, it is the job of certain cells, called microglia, to clean up that cellular debris. Microglia have counterparts called…

Obsessive compulsive disorder

The debilitating behaviours and all-consuming thoughts which affect people with severe obsessive compulsive disorder (OCD), could be significantly improved with targeted deep brain stimulation, according to the findings of a new study. OCD is characterised by unwanted intrusive thoughts (obsessions) and repetitive stereotyped behaviours (compulsions- sometimes called rituals) and often means…

Spatial cognition and neurodegeneration

Where are we coming from? Where are we going? Where are we right now? Our sense of spatial orientation – a complex interaction of various cells in the brain – gives us answers to these questions. In November 2018, around 70 experts in Magdeburg discussed changes in this navigation system induced by age and illness at the ‘Interdisciplinary Symposium on Spatial Cognition in Aging and…

At age 2

Researchers at the University of North Carolina School of Medicine used MRI brain scans and machine learning techniques at birth to predict cognitive development at age 2 years with 95 percent accuracy. “This prediction could help identify children at risk for poor cognitive development shortly after birth with high accuracy,” said senior author John H. Gilmore, MD, Thad and Alice Eure…

Restored brain waves

With a weak alternating electrical current sent through electrodes attached to the scalp, UNC School of Medicine researchers successfully targeted a naturally occurring electrical pattern in a specific part of the brain and markedly improved depression symptoms in about 70 percent of participants in a clinical study.

Some problems remain

Research in the past several years has shown that children can outgrow a diagnosis of autism spectrum disorder (ASD), once considered a lifelong condition. In a new study, researchers at Albert Einstein College of Medicine and Montefiore Health System have found that the vast majority of such children still have difficulties that require therapeutic and educational support.

Brain surgery

A minimally invasive procedure to determine whether patients with drug-resistant epilepsy are candidates for brain surgery is safer, more efficient, and leads to better outcomes than the traditional method, according to new research by The University of Texas Health Science Center at Houston (UTHealth).
